In the first quarter of 2015, McAfee Labs registered a 165 percent increase in new ransomware driven largely by the new, hard-to-detect CTB-Locker ransomware family, a new ransomware family called Teslacrypt, and the emergence of new versions of CryptoWall, TorrentLocker, and BandarChor. McAfee Labs attributes CTB-Locker’s success to clever techniques for evading security software, higher-quality phishing emails, and an “affiliate” program that offers accomplices a percentage of ransom payments in return for flooding cyberspace with CTB-Locker phishing messages.
